METHOD OF MAKING PICKS OR OTHER TOOLS.

- SPECIFICATION formingpart of Letters Patent No. 578,242, dated March2, 1897.

Application filed April 1, 1896. Serial No. 585,802. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM R. JENKINS, of Bellefonte, in the county ofCentre, and in the State of Pennsylvania, have invented certain new anduseful Improvements in Methods of Making Picks or other Tools; and I dohereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,in which- Figure 1 is aperspective view of the blank in the form of aT-shaped bar. Fig. 2 is a like view of the same after portions of theside flanges have been removed. Fig. 3 is a similar view of said blankafter the handle engaging ears or lugs have been bent to position, andFig. 4 is a perspective View of the same after the eye has been punched.

Letters of like name and kind refer to like parts in each of thefigures.

The object of my invention is to provide a method for the easy, cheap,and rapid manufacture of picks, hatchets, and other tools that, adjacentto the eye on each side thereof, have an ear or projection to overlapand engage the side of the tool-handle; and to this end said inventionconsists in the method employed in making tools, substantially as andfor the purpose hereinafter specified.

In the carrying of my invention into practice in the construction ofpicks I first form by rolling of suitable materialpreferably soft steelastraight bar that is T-shaped in cross-section, being composed of aheavy central body A and oppositely-projectin g flanges a and a. Fromsuch bar a piece of sufficient length is cut off to form the centralbody portion of the pick, and next portions of each of the flanges areremoved, as by stamping or shearing, to produce at the longitudinalcenter of the bar ears or projections a and a, one on each side. Saidears by suitable means are then bent at right angles to their originalposition, so as to lie parallel with each other, as shown in Fig. 3, andnext the portion of the metal of the bar A in line with the spacebetween said ears is punched out to form the eye for the reception ofthe handle, the result being shown in Fig. 4. The blank is now complete,except as to being given the customary curved shape, and when this hasbeen done the pick is finished by welding on the pointsteels in theusual manner.

As all of the operations involved in forming the eye-ears can be doneupon ordinary punching-machines, it will be seen that my method resultsin a better product and in the simpler, easier, and cheaper productionof the blank than is the case with the customary process, in which theeye is first punched from a simple plain bar and then the ears forgedout from the latter.

While I prefer the order of steps described hereinbefore, I Wish itunderstood that I do not limit myself thereto, as the order of theoperations may be changed without involving any departure from the scopeof my invention, and instead of employing a blank of the form shown inFig. 1, with the flanges projecting in opposite directions, a blank maybe used having said flanges projecting from the bar parallel with eachother in the direction in which the completed ears extend. I also wishit understood that I do not limit myself to any particular machinery ortools in the carrying out of my method.

Having thus described my invention, what I claim is 1. The methodemployed in making tools having ears projecting adjacent to the eyes,which consists in forming a blank comprising a body having flanges. atopposite sides, removing portions of each flange at each side of itslongitudinal center, and forming an eye through the body portion of theblank that is in line with the space between the remaining flangeportions, substantially as and for the purpose specified.

2. The method employed in making tools having ears projecting adjacentto the eyes, which consists in taking a blank comprising a body havingtwo oppositely projecting flanges, removing portions of the latter ateach side of the longitudinal center of each flange, bending theremaining portions of said flanges to cause them to extend outwardly inlines parallel, or substantially parallel, with each other, and formingan eye through the body portion of the blank that is in line With thespace between said flange portions after they have been so bent,substantially as and for the purpose shown.

3. The method employed in making tools having ears projecting adjacentto the eyes, which consists in taking a bar having twooppositely-projecting flanges so as to be T- shaped in cross-sectioncutting said bar into blanks, taking each blank and removing portions ofeach of said flanges, so as to leave a lug or car on each side of theblank, bending said lugs at a right angle to make them project outwardlyfrom the blank in the same 10 direction, and then forming an eye in the1 blank in line with the space between the lugs 017 cars, substantiallyas and for the purpose described.

In testimony that I claim the foregoing I have hereunto set my hand this4th day of 15 March, 1896.
